People with great intelligence offer great ideas and theories. There were several fields of science on which scientists performed in the past. The fields include chemical science, physical science, social science, environmental science, biological science, and natural science. Two of the great scientists of the past that are highly recognized in the field of natural science are Charles Darwin and Jean Baptiste Lamarck.

Charles Darwin, the English man, is a naturalist that postulated the theories of evolution, which believed that every creature has its own ancestors and that a creature evolves into another thing over a long period of time due to the inheritance of some acquired features. In the year 1859, he published a book titled "On the origin of species," which explains how creatures are evolved into what they are today.

However, Jean Baptiste Lamarck is French. He was a botanist and a professor in zoology, plus before which he was a soldier before he became a naturalist. He also worked further on the theory of evolution, proving that creatures evolve due to the part of the used and unused body.

The two scientists that gave theories on evolution are Darwin and Lamarck. The following explains the difference in their theories: Lamarck's theory of evolution was simply about how organisms (Plants and Animals) experience alterations during their lifetime and then pass these modifications across to their offspring.

Take, for example, Lamarck believes that as the first generation giraffe tried to reach leaves on high trees, the neck grew longer and this modification was passed down to the second generation giraffe, and subsequent changes were passed down to further generations—this resulted into the giraffe's neck is long.

In contrast, Darwin's theory of evolution, which is also known as natural selection, was based on the fact that organisms possessed distinct variations that make each organism slightly different from one another, and these variations led to some being more likely to survive terrible environmental conditions. It is from this idea that we get the phrase 'survival of the fittest.' Darwin's theory became accepted because it had more evidence that supported it, unlike Lamarck's theory.
